TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 264,091, dated September 12, 1882. Application filed March :27, 1882. (No model.)

To all whom it may concern Be it known that I, JOHN S. MARTIN, of and State of Ohio, have invented a new and useful Improvement in Type-VVriters, which improvement is fully set forth in the following specification and accompanyingdrawin gs, in which Figure l is an isometric view of the typewriter. Fig. 2 is a central vertical sectional view of the forward end of the vihratin g plate and type-disk. Fig. 3 is a perspective view of the rear end of the arm, showing the arrangement of the feeding mechanism for the paper. Fig. 4 is the same in different position, and Fig. 5 is an isometric view of the type-disk.

The object of this invention is to provide a type-writer capable of being manipulated with one hand by means of a holder or stylus.

It consists First. In having the letters of the alphabet, figures, points, &c., cast on the lower face of the disk, the said letters and figures being in relief and homogeneous with the disk. (Jenor spindle, which projects vertically through and is journaled in the forward end of a vibrating arm. The upper end of the arbor or spindle is provided with a hinged arm having a downturned end or point, which is provided witha V-shaped fork. To this arm is attached the lower end of the stylus or holder, which in writing is grasped by the hand.

Second. In providing a table directly beneath this elastic type-disk, with an ink-pad having an aperture or opening at one side slightly larger than the face of one of the letters or characters on the disk, so that the letter-paper beneaththe ink-pad will receive the impression of the letter or character which appears at the aperture in the ink'pad.

Third. In having the upper stationary face of the vibratingplate to which the revolving typedisk is jonrnaled provided with letters, characters, or figures in a circle to correspond with the letters and characters on the typedisk beneath, and each letter is provided with a radiating bar, so'that- 'the V'forked arm of the disk-arbor may be placed on said bars, as the different. characters or letters desired are successively selected by the operator.

Fourth. A vibrating arm having at its rear .paper,

end a retractile spring, and provided on the side with an adjustable latch for feeding the paper when the machine is in motion.

Fifth. A rack-bar sliding in a grooveiu the table beneath thepaper, with which the latch engages, having at the opposite end a transverse bar secured thereto, said bar being provided with a notched or serrated edge, to indi cate the distance of the lines on the sheet in writing; and,further, in having a sliding clasp secured to the transverse bar for holding the all of which will now be described in detail.

In the accompanying drawings, Arepresen ts the table to which the device is secured. This is provided with a groove, B, in its upper face,

running from end to end, preferably a little to one side of the middle of said table, as shown. In this groove is placed a sliding bar, B so that its upper faqe will be flush with the upper surface of the table. At its rear end, and secured thereto, is a rack-bar whose toothed edge projects over the side of the sliding bar B. To the forward end of the sliding bar B is attached a cord, which passes over the pulley O, and the lower or opposite end of the cord is equipped with a weight, D, so that the sliding bar, when not held by thefeeding-latch, will be drawn up to the V-pulley O or forward part of the table. 011 the forward end of the sliding bar is secured a transverse bar, E, havinga notched or serrated edge, E. On the transverse bar is a slide freely. To this sheath two curved springcatches, G, are attached in such a manner that their ends diverge from each other and extend past the opposite ends of the sheath, so that-their ends rest against the serrated or notched edge of the transverse bar E, upon which the sheath slides. The ends ofthese spring-catches thus rest in the notches E, so that the operator, in manipulating the machine, simply disengages the spring-catches from the said notches and slides the sheath up and down the transverse bar, as desired. The other side of the sheath has an extension (not shown) which projects under the paper H. On top of the sheath is a spring-lip, I, which projects over the paper H to hold it in positron.

Gent-rally on the table, and on each side of sheath,-G, adapted to i the latch on the stud away from the sliding bar B, is a stud, J. Between these i studs, and pivoted thereto,is a vibrating arm, K. The rear end of this arm is flush with the rear end of the table A, and is provided with an elastic, K, or retractile spring for the purpose of holding the rear end of the vibrating arm down onto the table.

On the side of the arm K, at the rear end, is a stud, L, which carries thereon a vertical latch, L. This latch is held on the stud by means of a pin, M; or a nut may be used for this purpose. A spring, M, is interposed between the arm K and latch L, so as to hold the arm. The lower end of the latch projects through a slot, N,in the table. This slot is of sufiicientlength to permit the latch to be moved in toward the arm K without binding. The latch-piece L, when in its normal condition, as shown in Fig. 3, is in such a position that its outer edge enters the teeth of the rack-bar G on the sliding bar B. At a suitable point on the edge is a recess or gain, N, and secured to the rear flat side of the latch is a flat spring, 0, which overhangs the recess N, the end projecting somewhat below the recess. The weight 1) tends to pull the rack-bar toward the forward end of the table; hence the tooth of the rack-bar presses against the flat spring 0 on the side of the latch-piece. As the "ihrating arm is raised the spring 0 guards the tooth of the rack-bar, preventing it from entering the recess N. When the lower end of the spring 0 passes above the rack-bar the spring retreats from the latch-piece L, and as the latch is again moved downward the tooth passes through the recess, permitting the succeeding tooth to rest against the spring 0 on latch L. As the tooth passes through the recess N the rack-bar and the transverse bar E, carrying the paper, move forward the distance of one tooth, allowing sufficient space for the operation of the next letter on the paper, and so on. The forward end of the vibrating arm has on its under side an elastic disk, 1?, on the lower face of which the letters, characters, &c., are formed in relief. These letters are preferably arranged in a circle. The elastic disk is se-' cured to a spindle, 1?, which passes through and isjournaled to the arm K, and on the upper end of the spindle is a cross-head, Q, to which are journaled, on opposite sides of the spindle, thebranchesRof an arm, It. Thefree end of this arm is turned downwardly at the end and has a -shaped fork, S. Secured to this end ofthe arm is the lower end of a holder or stylus, T, which is grasped by the hand. The holder or stylus may be attached to the arm R by means of a swivel or otherwise in a manner most suitable, so that the spindle 1 and disk can be revolved by the stylus withoutinconvenience. At the same time the outer end of the arm 1t may be raised and lowered a limited distance by the holder T.

U is a concentric annular groove in the upper face of the vibrating arm K to permit the downturned V-forked end S to enter at any point in its revolution. Radiating from the center and extending across this annular groove is a series of bars, V, secured on the outside of the groove to the vibrating arm by means of common screws V. On a line with each bar V on the periphery of the disk is a letter or character to correspond with the letter or character on the elastic revolving disk P below.

Beneath the revolving disk 1? is a thin inked pad, \V, secured along its inner edge X to the table. The forward edge of this pad has an opening or recess, X, point to correspond with the letters or characters type-.disk above, so that as the said type-disk revolves the various characters and letters will appear above the opening or recess X in the ink-pad. Between the elastic type-disk and the under side of the vibrating arm, directly above the aperture in the ink-pad, is a raised surface, Y, so that the letter or character which appears beneath the raised surface will more readily make an impression on the paper beneath as the vibrating arm is pressed down.

The operation will now be described.

he sheet of paper or letter-head is secured under the clip I, as shown in Fig. 1, and the opposite edge of the sheet put under the inkpad WV. The latch L is then pressed toward the vibrating arm K, so that it will clear the teeth of the rack-bar C. The transverse bar E, carrying the paper, is then moved up to the type-disk P, and the paper 11 adjusted by moving the shield Gr down on the transverse bar E to the point desired. The stylus T is then grasped by the hand, and the arm R raised, so that the fork S will clear the bars V, and rotated or turned until the fork appears over the letter-bar V, selected on the upper disk. The characters or letters on the revolving type-disk beneath are so arranged that a letter will appear over the aperture X in the ink-pad, similar to the one selected by the operator above. Thus should the operator put the forked arm 1% on the bar which indicates the letter Y a similar letter will appear at the aperture X in the pad. The fork S having been placed on the bar, the hand at the same time moves the stylus downward by a sudden impulse, causing the relief-type on the elastic plate to make the imprint of its character on the paper H.- The rear end of the vibrating arm is by this motion elevated, causing the spring 0 to appear above the rack-bar 0. As the rear end of the vibrating arm descends and the recess or gain N appears at the teeth of the rack-bar the weight forces the rack-bar forward "a equal to one tooth. The next tooth in the rackbar, being on the opposite side of the spring 0, is prevented from passing through. The apparatus is then in a position for the operator to repeat the process by selecting the next letter or character with the fork S and imdistance in the elastic herein shown appear the most suitable to accomplish the purpose.

Having described my invention, what I claim is 1. An elastic revolving type-disk on the under side of a vibrating arm, secured to a spindle and operated by means of a hinged arm secured to a stylus, as herein shown.

2. An elastic revolving type-disk on the under side of a vibrating arm having a swivel to which it is secured, and a cross head having a hinged arm forked and provided with a manipulating holder or stylus, in combination with radiating bars for receiving the forked arm, and letters or characters corresponding with the radiating bars, substantially as herein set forth:

3. In type-writers, the vibrating arm K, having at the rear end a retract ile spring, K, carrying a latch, L provided with arecess,N, and overhanging spring 0, with the sliding bar B, carrying a rack-bar, and the weight D, substantially as and for the purpose set forth.

4. Intype-writers, a table having the longitudinal groove 13 and the sliding barB, provided with a rack,O, and weight D, in combination with the transverse bar E, notched on one side, E, and carrying a sheath, G, pro vided with spring-arms G, and clip I, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of March, 1882, in the presence of witnesses.
